GRAPHICS LEVEL enables/disables the “small nuances” within WZAA.
It may also reduce the amount of CANNON fire and BARREL dropping.
In the above example, GRAPHICS : EFFECTS LEVEL is set to 1 and therefore the MUZZLE FLASH of the CANNON is displayed.
Disabling the EFFECT via the MCM will simply remove these “nuances” at the benefit of – perhaps – some increase in PERFORMANCE.
Unless you’re suffering badly in terms of lag, I’d leave this at default.
HOW DOES THE MCM WORK?
Disabling this may give a very minor performance boost.
Default = 1
0 = Off
